4.4: Treating depression Flashcards
(7 cards)
A researcher wanted to see whether cognitive behaviour therapy was an effective treatment for depression.
Twenty depressed patients who had all recently completed a course of cognitive behaviour therapy were involved in the investigation.
From their employment records, the researcher kept a record of the number of absences from work each patient had in the year following their treatment.
This was compared with the number of absences from work each patient had in the year prior to their treatment.
Those patients who had fewer absences from work in the year following their treatment than in the year prior to their treatment were classified as ‘improved’ (+).
Those patients who had more absences were classified as ‘deteriorated’ (-).
Those patients who had the same number of absences were classified as ‘neither’ (0).
The researcher decided to use the sign test to analyse the data.
The investigation is based on secondary data.
In what ways would the use of primary data have improved this investigation? (3 marks)
Primary data is obtained ‘first-hand’ from the participants’ themselves and so is likely to lead to greater insight

For example, participants may have taken time off work for reasons not related to their depression
